1. Which nutrient is most critical for preventing neural tube defects during pregnancy?

A. Iron
B. Calcium
C. Folic acid
D. Vitamin D

Correct answer: C

Rationale: Folic acid is the most critical nutrient for preventing neural tube defects during pregnancy. Neural tube defects are serious birth defects of the brain and spinal cord. Adequate intake of folic acid before and during early pregnancy can significantly reduce the risk of these defects. Iron, calcium, and vitamin D are important nutrients during pregnancy for other reasons, such as supporting the increased demands on the body for blood production, bone health, and calcium absorption, respectively.

2. Which of the following is a key principle of Primary Health Care (PHC)?

A. Centralized health planning
B. Community participation
C. Focus on specialized care
D. High technology healthcare

Correct answer: B

Rationale: Community participation is a fundamental principle of Primary Health Care (PHC) as it involves the active involvement of individuals, families, communities, and organizations in the planning and delivery of healthcare services. This ensures that services are culturally appropriate, accessible, and acceptable to the community, leading to better health outcomes.

3. When preparing a primigravida for breastfeeding, which of the following will you do?

A. Explain that lactation usually begins 1 to 3 days after delivery
B. Teach her nipple stretching exercises if her nipples are flat or inverted
C. Advise against washing her nipples excessively before and after each breastfeeding
D. Inform her that putting the baby to breast can help reduce post-delivery blood loss

Correct answer: D

Rationale: Putting the baby to breast can help reduce post-delivery blood loss as suckling stimulates the release of oxytocin, causing uterine contractions. Lactation typically starts 1 to 3 days after delivery, not immediately. Nipple stretching exercises are recommended for flat or inverted nipples, not everted ones. Excessive washing of the nipples can dry them out, increasing the risk of fissures.

4. During a home visit, the PHN bag is a crucial tool for providing nursing care. The most important principle in bag technique states that it:

A. Should save time and effort
B. Should minimize, if not totally prevent, the spread of infection
C. Should not overshadow concern for the patient and their family
D. May be done in a variety of ways depending on the home situation

Correct answer: B

Rationale: The bag technique is a vital practice to prevent the transmission of infections to and from the client during home visits. By following proper bag technique procedures, nurses can minimize, if not entirely prevent, the spread of infections between themselves and their clients, ensuring a safe care environment.

5. Which of the following health professionals can sign the birth certificate?

A. Public health nurse
B. Rural health midwife
C. Municipal health officer
D. Any of these health professionals

Correct answer: D

Rationale: According to R.A. 3753, any birth attendant, including public health nurses, rural health midwives, and municipal health officers, may sign the certificate of live birth. This law allows a range of health professionals involved in childbirth to be authorized to sign birth certificates, ensuring accessibility and convenience for parents.
